.Application filed December 3,1906. Serial No. 346,059. l

Be it, known that l, CHESTER B. WATTS, a citizen'of the United States, residing in the city of Winchester, in the county of Ran- Inclinometer, of which the following is a full, accurate,and lucid specification and exposiin the art to which it appertains to make and use the same with absolute exaetitude.-

`Broadly stated, my invention incorporates in a single-tool a level, a plumb, and an inclinometerl and comprising` in .its construcconnection with `said dials with means for accurately actuating said hands or pointers by gravity, substantiallyr as will be herein described in concrete detail and as shown in the accompanying drawings'.

provide a grav-ity plumb or level and incli-l tion, which will be positive in action, strong and durable in construction, neat and mechanical in appearance, and by the employment of which may be determinedy any degree of inclination, as well as the vertical or horizontal status, of any object to which it may be applied.

Probably the best .exemplification of the are `shown most clearly in the accompanying drawings, lin which Y Figure 1 is an upper edge view of my invention, showing a portion of the body in which elevation of the same; Fig. 3 is an 'enlarged central cross section, as taken on` the lme4 Fig. 5 is a central section as taken on the line Z-Z of Fig. 1; Fig. 6 is a side elevation of the revoluble disk; and Fig. 7 is a perspective Similar indices denote like parts throughout the several views ofthe drawings.

In order to render the construction and operation of my invention still more facile l will new take up a detail description thereof,

. lin which l will-set forth the construction and l uses of the invention as briefly and as com- 1 pactlygas I may. l

Figs. 3, 4, 5, 6 and 7 are made on a scale which may be termed actual size while Figs. 1 and 2 are on a reduced scale.

Referring now to the drawings in detail the numeral l denotes the body which may be of any suitable lengthy or material, and ordilnarily it may be a bar, usually of wood, of any preferred size.

. Centrallyof the body 1 a notch is. cut from wATTs, or WINcHEsTnR, 1NDrANA, AssIGNoR or ONE-HALF- To Josnrn wATTs, or' wINcHEsTER, INDIANA the upper edge down intoand across the body to receive the mechanism which. I will 'now describe.

Referring now to the invention proper:-

The numerals 2 and 3 denote the end members of the mechanism case; the numerals 4 i denote the sides thereof, and the The and 5 numeral 6 denotes the top of the same. sides and ends' are lsecured to ether by screws or the like forming a boxike receptacle which may be secured to and covered .by the .top 6, said receptacle being closed at the bottom by thebottom of the recess or notch in vthe body. .The width of the top G is such as to project out beyond the' sides, and in length such asl to project a considerable distance, comparatively, beyond the ends, the former being shown in Fig. 3, and the latter in Fig. 5'. for purposes which will presently appear.

Said projections being The'top 6 is let in ushwith the face of f thebod 1 where it is secured by the screws a vand In the center-.oftheltop 6 is a j s nare, inwardly convergingiy aperture 6 W ich is covered or'close'd-bythe glass-sight 7 secured to the underfsid'efo the top 6, as shown' in Figs. 8 and'. V

The sides 4-5 and .the endsl 2-3 are of a depth such as to rest on the bottom ofthe said notch in the body 1, when the top 6 isin position as specified. Formed throughthe sids`4 and 5 arecircular apertures 4 and 5',

. respectively. To the backs or'inner faces of the-sides 4 and 5 are secured the respective -dials S and 9 which close said respective apertures 4 and 5, each having a circular graduated scale thereon, indicated by the numerals 10 and 11, respectively, andeach being divided into groups indicated by numerals ranging progressively in both directions from 0, at the central upper part, to at the lower central part of said dials.. Formed through the center of each of saiddials are the .respective apertures 8 and 9', for the purposes presently appearing.

IOC'

verably of lead or other heavy material.

Of same size and covering the faces of the sides 4 and 5 are the respective crystals 12 and 13 which cover their respective dials but are spaced therefrom by the said sides as is. shown in Fig.

The numerals 14 and 15 denote face-plates contacting', at their upper edges, with the outer edges of the top (j, being'of same length as the top 6, and extending down. below the sides 4 and 5 to obtain a lateral bearing against the body, and being letin flush with the sides of the body 1, all substantially as shown in Fig. 3. Iformed through the faceplates are the respective outwardly flaring circular apertures 14 and 15 which correspond with the respective apertures 4 and 5, as in Fig. 3. The faces of said plates 14 and 15 are flush with the respective sides of the body 1', as indicated in, Fig. 1, where they may be secured by a plurality of screws or the like as, for instance, the screws c, d, e, and

f, in Fig. 2.

Secured to the backs egf the dials 8 and 9, around the central apertures 8 and 9, are the bosses 16 .and 17 respectively,through which passes the shaft .18. Said shaft protrudes outward at each end slightly beyond the faces of the dials to receive thereon the hands, or indicators, 19 and 20.

Securely mounted on the shaft 18, between the bosses 16 and 17, is the comparatively large two-part disk composed of the members A and B, which members may be secured together in any preferred manner. Said disk should be composed vof wood or other light material.

The letter C denotes a weight formed psf- 1e center part of said weight extends out iiush and corresponding with the periphery of the disk, between the members of which it is contained, there being lugs extending out integral with and from each side of Athe weight which lugs pass through apertures therefor formed through the side of each of the members A and B, as is indicated inthe drawings, whereby when the weight is po- -sitioned and the members of the dlsk are secured together the weight will be locked against removal in any direction as shown.

Secured around the periphery of the disk is a band or endless strip D, containing therel on a series graduations indicated by nuglass 7, there being an indicating. or centering merals from "0 to 180, being indicated progressively in both directionsfrom U0, which is directly opposite the center of the weight C, to 18D which4 isdirectly over the center of the weight C. Said band or strip-D is so located that the graduations and figures thereon may be observed through the and 9.

the glass 7 to indicate its center. When constructed as set forth the arrangement of said parts are such that when the l mark 7 cut into or otherwise made across l under edge of the body 1 is resting on a level surface the weight C will, obviously, retain the disk normally in the position shown in Figs. 3, 5 and 6, with the indication mark "0 on the band DA directly and centi ally under the line 7, that is to say,-centrally of the glass sight 7. At same time the hands 19 and 20 will be pointing directly upward, that is to the 0s on the respective dials 8 body 1 be raised up it is apparent that the weight C will by gravity prevent the disk from turning, but will adjust the disk by gravity whereby the hands 19 and 20 will continue to point directly upward, and as theI dials have been turned by the raising of one end of the body it will be seen that the hands will assume new points on the dials thereby indicating new graduations on the dials, and at the same time a new number will appear under`,the line 7, and the new graduating marks indicated by the hands and below the line 7 will indicate the inclination assumed by' the body 1.

Itis also apparent that if the body is placed in a vertical position the indicators will register at While if the body be turned entirely over to the horizontal then fest that any degree of inclination may be determined, at the points, between the two extremes.

I Ahave herein described the best exem liication of my invention t'o me known at t is time but I desire that itfbe understood that various changes and variations may be made in the details thereof Without departing from the spirit or sacrificing the advantages of my invention.Y y

Havingwnow given a complete exposition of my invention, what I claim and desire to secure by Letters Patent of `the United States, 1s-` 1. In a gravity plumb-level and inclinorneter, a body aving a transverse recess formed entirely therethrough, a boxing having side and end walls seated within said recess, said side walls being' provided with a ertures and being set in from the sides of t e body, an apertured top plate overlying said boxing and having its en ds extended beyond the end walls thereof, securing means passing through such extended ends into said body, alpertured face plates fluslijwith the sides of t e body and having 'their u per portions bearing laterally against the si e edges of the top plate and their lower portions extended below the boxing and bearing laterally 'against the body,'means for securing said face plates in place, and glasses mounted in conjunction with the several apertures g in combination with a pair of dials mounted in conjunction, with the apertures of the side walls of the boxing, a peripherally-graduated weighted disk suspended. rotatively be- Now for instance if one end of the they will indicate 180, and it is also mani- I TOO TIO
